Synchronisation of sound and vision

[Tore Nilsen]

You will have to use the callbacks property of the player to do what you want to do. The callbacks list would be your cues. From the dictionary:

The callbacks of a player <> is a list of callbacks, one per line. Each callback consists of an interval number, a comma, and a message <> name.

I see that one would inevitably have to add cues to the spoken text file to fire off the highlighting, which is indeed an unavoidable amount of work, but can it be done at all in LC? For example, what form would the cues take?
